The next step is adding some protection, because maybe we don't want to allow _anyone_ to write to our relay. Maybe we want to only allow people that have a pubkey starting with `"a"`, `"b"` or `"c"`:
```go
relay.RejectEvent = append(relay.RejectEvent, func (ctx context.Context, event *nostr.Event) (reject bool, msg string) {
relay.OnEvent = func (ctx context.Context, event *nostr.Event) (reject bool, msg string) {
firstHexChar := event.PubKey.Hex()[0:1]
if firstHexChar == "a" || firstHexChar == "b" || firstHexChar == "c" {
return false, "" // allow
}
return true, "you're not allowed in this shard"
})

There are many other ways to customize the relay behavior. Take a look at the [`Relay` struct docs](https://pkg.go.dev/fiatjaf.com/nostr/khatru#Relay) for more, or read the pages on the sidebar.
